HYDRAULIC PACKERS
RHP – DB DUAL BORE HYDRAULIC SET RETRIEVABLE PACKER
The ACT MODEL RHP-DB Retrievable Packer delivers high performance with simplicity of design and desirable economics. The dual bore packer allows for a large ID through the packer by sealing in an upper seal bore. No tubing rotation required to fully set the packer. It has one-piece, self energizing packing element and features bidirectional slips below the packing element for maximum protection from debris fouling. This location protects the slips from being lost during retrieval or milling. A retrieving tool is required to retrieve these packers.
FEATURES:
- Simple design
- Easy to retrieve
- Large seal bore
- Hydraulic setting
- Hydraulically setting the packer avoids the need to rotate the work string in running or retrieving the packer, which simplifies procedures, improves efficiency, and saves rig time.
- The ECNER array system reduces the swab-off effect and facilitates center pack off by enabling supporting force to be applied to the outer elements.
ERD RETRIEVABLE SEAL BORE PACKER
ACT Model ERD Retrievable Hydraulic Seal Bore Packer is a Retrievable Packer. Hydraulically set by pressure in the tubing. It is run with Hydraulic Setting Tool & retrieving is done independently from the Tubing, using a Retrieving Tool manipulated on a work string. This packer is ideally suited for highly deviated well both onshore & offshore.
APPLICATIONS:
Model ERD Retrievable Hydraulic Seal Bore Packer can be use in oil production wells or in water or gas injection wells.
FEATURES, ADVANTAGES AND BENEFITS:
- Run & set with the Production Tubing
Hydraulically setting eliminates the requirements for spacing out & opening & closing with the help of Sliding Sleeves for the displacement of fluids - Effects on tubing (compression & tension) are transmitted to slips- there is no shear ring with limits these stresses
- Retrieval independent of the tubing using a Retrieving Tool. It can be lift to the bottom of the well with a By-Pass Blanking Plug in a Nipple to isolate the formation
MODEL FURY 25 HYDRAULIC SETTING TOOL
MODEL RHP-SR RETRIEVABLE HYDRAULIC PACKER SINGLE STRING
American Completion Tool Model RHP-SR is a hydraulic set packer that can be run in single or multiple zone installations. It is highly recommended for deviated wells where conditions are not suitable for mechanical or wireline set packers. No tubing movement is required or generated in order to set the packer. This allows the well to be kept positively controlled at all times because the tubing is landed and the wellhead installed before circulating or displacing well fluids prior to setting the packer. Two or more packers can be set either at once or in any desired sequence.
The RHP-SR packer design features bi-directional, one piece slips located below a three element packing system consisting of dual durometer rubber elements. The slips are fully enclosed in a shear pinned slip housing which in turn is protected by a full diameter guide located below the slip housing. The RHP-SR packer requires a means of establishing a maximum of 3,500 psi pressure inside the tubing at the packer (for 7″ and smaller).
The hydraulic setting chamber is adjustable between 900 to 2,500 psi which allows the tubing to be pressure tested before the packer begins to stroke and set. Two balanced pistons are utilized during the setting process. The lower piston moves down to set and anchor the slips before the upper piston moves upward to compress the packing. This action imparts the total setting force to both slips and packing thus assuring a positive anchor and pack-off. The pack-off is retained by a one-piece ratchet ring that locks in and stores the setting force applied to both the slips and packing elements.
The RHP-SR packer incorporates two methods of release, straight pull or rotation. Both methods are contained in the same releasing nut which is located at the upper end of the packer. Straight pull release is accomplished by shearing a predetermined quantity of brass retaining screws which frees the tubing. Rotation release is accomplished by approximately eight right hand turns of the tubing which also frees the packer. Straight pull then is applied to completely relax the packer for retrieval. The RHP-SR packer can be ordered with only one method of release if desired. A positive acting equalizing valve is also located in the releasing section which automatically opens during the releasing procedure to equalize pressures and allow circulation between the annulus and tubing. In addition, a large diameter fluid by-pass is located inside the packing mandrel which allows fluid passage for rapid retrieving while reducing element swabbing.
RHP-SPR HYDRAULIC SET RETRIEVABLE PACKER
The ACT RHP-SPR Packer is a hydraulic set single-string retrievable packer and may be used in virtually any production application. Tubing pump pressure is used to set the packer and the setting force is locked into the packer by a body lock ring. A large internal by-pass reduces swabbing when running and retrieving. The by-pass closes when the packer is set, and opens during the releasing process to allow pressure equalization. Shear screws are used to control the packer release. The shear release value is adjustable by adding or removing screws from the shear housing or by use of steel screws. The standard ACT Packers are designed for differential pressures up to 7,500 psi.
FEATURES:
- The straight-pull, shear-release pins are unaffected by differential pressure, enabling easy changes to the release force before running
- The double-grip system enables the packer to hold differential pressures
securely from above and below, preventing packing-element movement and ensuring proper pack off
All components are locked to prevent pressure build up or debris from pre-setting the packer, improving reliability when running the packer in the wellbore - Adjustable shear release
Straight pull release
POLISHED SEAL BORE RECEPTACLE
The ACT Polished Seal Bore Receptacle is designed for applications where a large ID must be maintained through the completion while accommodating extreme tubing movements. The ACT Polished Seal Bore Receptacle modular design allows tool to be easily converted from tension release to hydraulic release. The tension release and the hydraulic release incorporate a Polished Seal Bore Receptacle as well as a PBR seal assembly including 2 sets of working seal units and a debris barrier above and below the working seals. Both versions when combined with a hydraulic or hydraulic/ hydrostatic set can be run in and set in one trip. The polished seal bore receptacle can be retrieved in two trips. The seal assembly is retrieved when the tubing string is recovered. The PBR seal bore is retrieved with a PBR retrieving tool. The Polished Seal Bore Receptacle is available in varying lengths of up to 25 ft. in stroke. An adjustable shear mechanism locks the outer housing and seal mandrel together during run- in. Once the seal assembly is released, it is free to move in the bore, compensating for tubing movement. The PBR assembly can be pinned in the fully stroked, closed or midway position to accommodate pre-spacing in one-trip completions.
APPLICATIONS:
- One-trip installations in deviated or horizontal wells
- Large-bore, high-flow-rate applications

OVERSHOT EXPANSION JOINT(OEJ) ASSEMBLY
ACT Overshot Expansion Joint (OEJ) Assembly is designed for applications where extreme tubing movements are expected due to stimulation or production of the well and when a tubing separation device is also required.
The OEJ assembly is a one-trip system, which allows the well to be flanged up prior to setting the packer. The OEJ assembly incorporates a slick joint sub as well as housing – packing set including working seal units and a debris barrier above the working seals. The plain receptacle, housing – packing set and seals can be retrieved when the tubing string is recovered for maintenance or the entire completion can be retrieved by straight pull after ensuring that J-pin engaged with J-slot, thus allowing the packer to be retrieved.
The OEJ assembly is available in varying lengths of up to 20 ft. stroke. Adjustable shear pins lock the inner & outer assembly together during run-in. Once the shear screw gets sheared by applying load, the outer assembly gets disengaged and it is free to move on the inner assembly, compensating for tubing movement.
